Department of Energy gives NVIDIA $12.4 million to help create power-efficient exascale comptuer

Computer graphics chip maker NVIDIA recently announced that the US Department of Energy has granted it a two-year, $12.4 million contract for the research and development of exascale computer technology. The scientists and engineers from the government and the private company will work together to advance the field and produce an exascale computer that operates at a "reasonable" power level. The focus will be on developing processor architecture, circuits, memory architecture, high-speed signaling, and programming models.

Thousands of throughput-optimized cores will handle the majority of the heavy lifting, while some latency-optimized cores will do residual serial computing. Seven Department of Energy laboratories will guide NVIDIA as to what kind of scientific workloads the exascale computer will need to handle.

There are some other companies receiving grants from the government as part of its FastForward program. It requires the processing of demanding scientific and technical computing loads. An exascale system will be required to perform a quintillion floating point calculations per second, or 1,000 times faster than a one petaflop supercomputer. The fastest supercomputer currently in operation tops out at about 16 petaflops and uses 1.5 million cores.

The DoE hopes to build an exascale system that consumes less than 20 megawatts of power before 2020.

Cirrus creates Lightning-headphone dev kit

Apple supplier Cirrus Logic has introduced a MFi-compliant new development kit for companies interested in using Cirrus' chips to create Lightning-based headphones, which -- regardless of whether rumors about Apple dropping the analog headphone jack in its iPhone this fall -- can offer advantages to music-loving iOS device users. The kit mentions some of the advantages of an all-digital headset or headphone connector, including higher-bitrate support, a more customizable experience, and support for power and data transfer into headphone hardware. Several companies already make Lightning headphones, and Apple has supported the concept since June 2014. http://bit.ly/29giiZj

Apple Store app offers Procreate Pocket

The Apple Store app for iPhone, which periodically rewards users with free app gifts, is now offering the iPhone "Pocket" version of drawing app Procreate for those who have the free Apple Store app until July 28. Users who have redeemed the offer by navigating to the "Stores" tab of the app and swiping past the "iPhone Upgrade Program" banner to the "Procreate" banner have noted that only the limited Pocket (iPhone) version of the app is available free, even if the Apple Store app is installed and the offer redeemed on an iPad. The Pocket version currently sells for $3 on the iOS App Store. [32.4MB]

Porsche adds CarPlay to 2017 Panamera

Porsche has added a fifth model of vehicle to its CarPlay-supported lineup, announcing that the 2017 Panamera -- which will arrive in the US in January -- will include Apple's infotainment technology, and be seen on a giant 12.3-inch touchscreen as part of an all-new Porsche Communication Management system. The luxury sedan starts at $99,900 for the 4S model, and scales up to the Panamera Turbo, which sells for $146,900. Other vehicles that currently support CarPlay include the 2016 911 and the 2017 models of Macan, 718 Boxster, and 718 Cayman. The company did not mention support for Google's corresponding Android Auto in its announcement. http://bit.ly/295ZQ94

Apple employees testing wheelchair features

New features included in the forthcoming watchOS 3 are being tested by Apple retail store employees, including a new activity-tracking feature that has been designed with wheelchair users in mind. The move is slightly unusual in that, while retail employees have previously been used to test pre-release versions of OS X and iOS, this marks the first time they've been included in the otherwise developer-only watchOS betas. The company is said to have gone to great lengths to modify the activity tracker for wheelchair users, including changing the "time to stand" notification to "time to roll" and including two wheelchair-centric workout apps. http://bit.ly/2955JDa

Twitter stickers slowly roll out to users

Twitter has introduced "stickers," allowing users to add extra graphical elements to their photos before uploading them to the micro-blogging service. A library of hundreds of accessories, props, and emoji will be available to use as stickers, which can be resized, rotated, and placed anywhere on the photograph. Images with stickers will also become searchable with viewers able to select a sticker to see how others use the same graphic in their own posts. Twitter advises stickers will be rolling out to users over the next few weeks, and will work on both the mobile apps and through the browser. http://bit.ly/29bbwUE
